To all whom itmay concern:

Be it knowi'i that l, UlL-kUIHJGY W. GAY, a pitizrn ot' the United States otumericzt, and resident. of Vi'est lFlpringlicld, in the county of Hempdcn and State of Zilussochusetts, have invented certnin new and useful improve ments in Machines for Surface Finishing Paper, of which the following is it full, clear, and exact description.

My present iuvcn lion has ,iorits objects certain improvements to my prior Ptilliillt-Kl mo chines, which patents are numbered 778,126 and 705,355. Among the more characteristic end salient.- lostures of suid patented n'snchines are co-ucting, rotating, suitably covered cylii'idcrs or rol eiich carrying in l ex tending t-lumnci or depression on nutomutirnllyen'touted g ip'pcr, one grigmor thrleuding cud ol-tho blttllk ol lending ends of the paper blunks taken by the grippers are not finished by (he surfacingcylindors, they are more or less mutilated by the grippers, and trin'uning oil' ol' each of the leading ends, soy one-hall to one inch, is nocessitated, consuming time, labor, and stock.

One of the lending objects, therefore, of my invention is to do away with the grippers and. the necessity for their use, and so to construct and combine the elements of my present invention that the paper to be operated upon may be fed from a supply-roll in one long, continuous sheet, and, also, thnt,every portion of the paper operated upon may be utilized every part ol' the paper being given the desired finish in vcrisinnlitude of cloth, no inutilntions occurring, with consequent loss of time labor, and money, in trimming.

With this most important object in view mrticularly, and withother minor obj cots of improvement which will appear as the speoification proceeds and the invention, as it .rying it hetwccu the 'lirst und tion, combination, and arrangement of parts as fully herelnnfter set forth in the specification, summed up lIl' the chums, and illustrated in the drawings, in which letter:

Figure 1 is a planview of the machine constituting my present invention; Fig. 2 is a view in the nature of a side elevation; Fig. 2 is a detail view of an adjusting mechanism, more clearly illustrating the some parts shown in dotted lines elsewhere; Fig. 3 is a view similar to Fig. 2, out looking at the machine from the opposite side; and Figs. 4, 5, and 6 are detail sectional views of the threehigh rolls or cylinders, with'the puper therebetween,showing graphically the operation upon the paper at difl'oront points in the revolution oi the cylinders.

Now, referring in detail to the drawings, Y

represents :1 il'rmnc for the working parts oi my machine, and which, among other ports, supports, in appropriate hearings therein, o supply-roll Z of paper, to be operated upon, which roll is wound upon a journal-shalt L carrying at one or at. either end a pulley 2, over which posses u strap, or the like, 2", one end thcrcol' being secured againstmovement and the other end carrying ii weight 2, whereby proper tcnsionii'ig oi" the supplyroll is effected. Vv'hile other means of ten sioning may be used have devised the form disclosed as being pzu'ticularly eil'ective for the )urpose intended. Also mounted. in suitable hearings in the lrtune are, as disclosed in the drawings, ev set of three-high rolls or cylinders, l, 2, 3 (most clearly shown in Figs. 4, 5, end 6 but it is to be understood that this is merely for the sake of illustration,-in foot, in )rnctice, I )referably use a set of six-high re s or cylin ers (a set additional to and identical with the set shown in the drawings being superposed upon the so shown). demonstrations in. racticnl use, to have the set of three-high ro ls shown, numbered 1, 2,

and 3,,periphcrally covered with. cloth, and to have the ren'iaining set of three-high rolls (not shown) covered with cloth overlaid endsofthe c oth-covcring are suitably secured, these channels being a feature common elso'to In patented structures; nut it may be here stated that the'function of the the invention consists in the novel construc- I have found it desirable, by

2'0 'the slot v and the blocks (1, as shown clearly in the drawings.

' sinking of the ends of the cloth have metand overcome a long-felt dilliculty.

The cylinders (see Figs. 2 and 2) are each supported, at either end, in a bearing-block (l,-1nom1ted in a slot 1* in a standard. V ol' the frame; of the machine; the upper one of said blocks (1 having a desirably flat top and an inclined or beveled base d, the middle block having both an inclined top and an inclined base, the two inclines converging, and the lowermost block having an inclined top and a llat base.

Between each two adjacent blocks (1 is disposed a wedge block fol lesser width than Passing transversely through the sides of the standard V are threaded adjusting.

serewsf (shown in dotted lines in Fig. 2 and in full lines in Fig. 2) b aring against the wedges whereby the wedges'maybe driven horizontally either to the rightor to the lelt, causing consequent vertical movement of the blocks d, for properly positioning the axis of one roll or cylinder relatively to the axis of the adjacent roll, according to the thickness of the paper to be operated upon, 01 t0 the degree ol pressure to which the paper is to be subjected. lt will be observed, also, that the blocks (I, (re-acting with the wedgesf, prevent the rolls or cylinders collapsing or settling together, when the longitudinally-extending channels or depressions X of two adjacent rolls come into register. Passing through the cap piece g ol each i of the slotted standards V is a tbremled setscrew g, bearingagainst the top ol the upper block (I, and assisting in regulating the pres sure of the collective rolls or cylinders.

The mechanism for operating the rolls comprises a driving-shaft A carrying at one end a pinion 12 meshing with a spur gear wheel 13 carried by a eountershal't 14, which carries at its opposite end a. pinion 15. meshing witha s ur gear wheel 16 on the extended journal of t 1e lower elotl1- -overed cylinder 1.

The cylinder 2 is provided with a. spur gear wheel 18 meshing with a spur gear wheel 16', and cylinder 3 has a spur gear wheel 1 meshing with a spur gear wheel 18, whereby all three cylinders rotate at uniform speed in the directions ol the arrows, Fig. :4.

Now, I come to one ol the leading features of my present invention, and one which goes far to make up the general excellence and practicability ol my improved machine, and attention ishere invited to Figs. 4, 5, and 6: It will be readily seen that the paper in passing between the rolls l and 2, of equal size,

would have a cross-stripe therein at the point marked at, or where two longitudinally extending channels X register, and which would not be subjected to the finishing action of the cloth-coverings b of the rolls 1, 2

, provision oi the rollers the sheet of pa per is caused totake a detour, it were, whereby the portion a; ol'the paper, which has not been subjected to the action of rolls 1 and because ol the registering tmsition, there, of

the channels X, is caused to take an (axtended travel, so that,,1nstea .l. of arriving at the registering posi on of the channels X in rolls 2 and f) as it otherwise would, were the roller l3 not provided), it is brought. to a.

position to pass between nnrecessed or una channeled peripheral portions ol rolls 2 andB, as unheated most graphically at the point; :1", Fig. (3. Bi1elly, l l1( result t n-comphshed is that the portion of the papensheet which is not ellith-surlaeed in its passage between rolls l and l, is subjected to the surfacing action between rolls 2 and 1- making them!- tire surface, througlnjiul the entire length, of the paper, absolutely nnil'orm.

When the rolls 2 and ii are in the position shown in Fig. 4, with the channele il portions of rolls 1 and f2 registering, the paper is loose lrom the nipping or biting pointbetween rolls 2 and 2% clear back to theten-E sioned supply-roll 7., whereby the-paper may (which be strete \((l, or have any wrink are apt to form where the lirst two rolls"- laken out;

loosen their hold on thesheet. This feature, also, is of importance, ascou tribuling to the general reliability ol machine for doing perfect work.

For carrying the pa per sheet.forward onto a receiving table or c lute .l),"commonl'eeth ing-tapes, or the like, i, '1', may advantageonsly be utilized, and are-desirably driven by a. sproclzetazlmin i running around a sprocket on the end ol" the tape pulley shaft 50 and also around a sprocl et-wheel 51 on a shaft 52, which is driven by a chain 53 running around'a sproeliet-wheel 54 on one end ol cylinder 1 and around another sprocketwheel 55 on said shaft 52.

For cutting oil the sheets which are laid on the receiving table l) a shear device is utilized, F representing a stationary shearblade, and (i a revoluble blade carried by arms (1' extending lrom a shalt 3O driven my the a spur-gear 32 in mesh with a spur gear 33 on an extended journal of the cloth-covered cylinder 2. i

It will be understood that the set of threehigh rolls or cylinders, m'eviously mentioned as not being shown. in the drawings, but which are superposed upon the set of rolls 1, 2 and 3, are identical with said rolls 1, 2, and 3, even to the provision ot a roller B, acting in conjunction therewith.

It is obvious that my invention, in its minor details, is susceptible of slight changes; and all such immaterial changes, not all'ecting the spirit of my invention, come strictly within the scope and purview thereof.

As the present machine is designed, and as the same has been described, the rolls or cloth surfacing cyliinlers are in vertical stacked arrangement. and their journals, journal boxes, and the wedge shaped distancing blocks are in vertical alinement, but obviously inversions or other arrangements of the essential or desirable operative parts may be made in a manifest ma.nner,the machine may, or may not, have the cutting off shear and sheet delivering means shown,

the surface finished paper may be run in a continuous web onto a take-u roll therefor and thereafter handled in any desirable manner, or the machine may be combined as an entirety with other machinery, for paper manufacture. a

While this machine is possessed of fully, or more than double the operative ca ability of my heretofore patented cloth mishing machinesand is operative by the requirement of less tending, and without waste of stock, it has a large number of times greater elotlrfinishing capacity than the ordinary lating machines which can only be operated by the exercise of" much hand labor, preparation and constant attendance.
